        <p>
            Texturing allows elements of an image array to be read by shaders.
        </p>
        <p>
            <code class="function">glCompressedTexImage2D</code> loads a previously defined, and retrieved, compressed two-dimensional
            texture image if <em class="parameter"><code>target</code></em> is <code class="constant">GL_TEXTURE_2D</code>, or one of the
            cube map faces such as <code class="constant">GL_TEXTURE_CUBE_MAP_POSITIVE_X</code>.
            (see <a class="citerefentry" href="glTexImage2D.xhtml"><span class="citerefentry"><span class="refentrytitle">glTexImage2D</span></span></a>).
        </p>
        <p>
            If <em class="parameter"><code>target</code></em> is <code class="constant">GL_TEXTURE_1D_ARRAY</code>, <em class="parameter"><code>data</code></em>
            is treated as an array of compressed 1D textures.
        </p>
        <p>
            If <em class="parameter"><code>target</code></em> is <code class="constant">GL_PROXY_TEXTURE_2D</code>, <code class="constant">GL_PROXY_TEXTURE_1D_ARRAY</code>
            or <code class="constant">GL_PROXY_TEXTURE_CUBE_MAP</code>, no data is read from <em class="parameter"><code>data</code></em>, but
            all of the texture image state is recalculated, checked for consistency,
            and checked against the implementation's capabilities.  If the
            implementation cannot handle a texture of the requested texture size, it
            sets all of the image state to 0, but does not generate an error (see
            <a class="citerefentry" href="glGetError.xhtml"><span class="citerefentry"><span class="refentrytitle">glGetError</span></span></a>). To query for an entire mipmap array,
            use an image array level greater than or equal to 1.
        </p>
        <p>
            <em class="parameter"><code>internalformat</code></em> must be a known compressed image format (such as <code class="constant">GL_RGTC</code>)
            or an extension-specified compressed-texture format.
            When a texture is loaded with <a class="citerefentry" href="glTexImage2D.xhtml"><span class="citerefentry"><span class="refentrytitle">glTexImage2D</span></span></a> using a generic compressed
            texture format (e.g., <code class="constant">GL_COMPRESSED_RGB</code>), the GL selects from one of
            its extensions supporting compressed textures.  In order to load the
            compressed texture image using <code class="function">glCompressedTexImage2D</code>, query the compressed texture image's
            size and format using <a class="citerefentry" href="glGetTexLevelParameter.xhtml"><span class="citerefentry"><span class="refentrytitle">glGetTexLevelParameter</span></span></a>.
        </p>
        <p>
            If a non-zero named buffer object is bound to the <code class="constant">GL_PIXEL_UNPACK_BUFFER</code> target
            (see <a class="citerefentry" href="glBindBuffer.xhtml"><span class="citerefentry"><span class="refentrytitle">glBindBuffer</span></span></a>) while a texture image is
            specified, <em class="parameter"><code>data</code></em> is treated as a byte offset into the buffer object's data store.
        </p>
        <p>
            If the compressed data are arranged into fixed-size blocks of texels, the pixel
            storage modes can be used to select a sub-rectangle from a larger containing rectangle.
            These pixel storage modes operate in the same way as they do for <a class="citerefentry" href="glTexImage2D.xhtml"><span class="citerefentry"><span class="refentrytitle">glTexImage2D</span></span></a>.
